Slope measured at any point on V

waveform.
2
Ramtron cannot test or characterize all V
DD
power ramp profiles. The behavior of the internal circuits is difficult to predict
when V
DD
is below the level of a transistor threshold voltage. Ramtron strongly recommends that V
DD
power up faster than
100ms through the range of 0.4V to 1.0V.
